Exam 15: The Urinary System

In a 24-hour period, a typical volume of urine production is ________.

The blood vessel directly feeding the glomerulus with blood from the cortical radiate artery is the ________.

Identify the urinary structure with its associated description: A) renal vein B) renal medulla C) calyces D) renal pelvis E) renal (medullary) pyramids F) renal columns G) renal cortex -Cortex-like extensions that separate the renal (medullary) pyramids

Dilute urine would have a specific gravity closest to ________.

The inability to voluntarily control the external urethral sphincter is known as ________.

Explain how tubular reabsorption and tubular secretion are nearly opposite processes.

Blood proteins and blood cells are too large to pass through the filtration membrane and should not be found in filtrate.

The involuntary internal urethral sphincter is composed of skeletal muscle.

Identify these organs of the urinary system with their associated descriptions: A) ureter B) urethra C) urinary bladder -Tube that drains urine from the kidney to the urinary bladder

What stimulates the release of renin from the juxtaglomerular (JG) apparatus?

Identify the process that occurs in the kidney. A) tubular reabsorption B) glomerular filtration C) tubular secretion -Water, glucose, amino acids, and needed ions are moved from the filtrate back into the blood

Compare and contrast filtrate from blood plasma.

Using Figure 15.1, identify the following: -A calyx is indicated by ________.

The region of the renal tubule closest to the glomerular capsule is the distal convoluted tubule.

Identify these organs of the urinary system with their associated descriptions: A) ureter B) urethra C) urinary bladder -Muscular sac suitable for temporary urine storage

The medial indentation where the ureter, blood vessels, and nerves are connected to the kidney is called the ________.

What region of the kidney is deep to the renal cortex?

The process of emptying the urinary bladder is referred to as voiding or ________.

Using Figure 15.2, identify the following: -The nephron loop, or loop of Henle, is indicated by ________.

A strong acid will dissociate and liberate more ________ ions in water than a weak acid.
